Aaron Siego of KDE: "It would be very nice if our X server could use OpenGL directly for its display and composition. Because then we could have hardware accelerated effects that are not only cool looking, but also very useful. Well, there is just such a project underway, called XGL. But don't hold your breath. The development of XGL has been largely removed from the community and is being done behind closed doors. Who is this company, you ask, that would take the development of something as potentially important as this out of the community and put it behind closed doors? Novell."

i am not talking about that particular license. i am talking about that attitude in some projects, that if something is not pure open source or developed "the open source way" it should not exist.
I am talking about the binary drivers issues, the mono issues etc...

Well because the software can't be distributed freely like EX: ubuntu discs, without agreeing to the EULA of the closed software (EX: see adobe reader license) , the opensource licenses does give you that permission.
The vendor themself must actually give you permission to include it.

And let's not mention the patented software.
